Potato pulp fermented feed and preparation method thereof

Abstract

The invention discloses potato pulp fermented feed and a preparation method thereof and relates to the field of preparation of animal feed from plant materials. The potato pulp fermented feed is prepared by using 75 to 80 percent of potato pulp, 10 to 15 percent of dried date powder and 5 to 15 percent of defatted rice bran as raw and auxiliary materials, adding 0.75 to 1.5 percent of urea, 0.75 to 1.5 percent of ammonium sulfate, 0.5 to 0.7 percent of monopotassium phosphate and 0.4 to 0.6 percent of magnesium sulfate on the basis of the raw and auxiliary materials, mixing to form a fermentation substrate, preparing a combined fermentation strain solution from bacterial liquid of bacillus subtilis, saccharomycopsis fibuligera, aspergillus niger and lactobacillus plantarum, carrying out aerobic fermentation and then carrying out anaerobic fermentation, wherein the weight ratio of the fermentation substrate to the combined fermentation strain solution is 1:(1 to 1.2); a volume ratio of four types of bacterial liquid is (1 to 3):(1 to 3):(1 to 3):(1 to 3). According to the invention, the amount of true proteins in the fermentation substrate can be increased; the amount of crude fibers is reduced; palatability and a digestive utilization rate of the feed are improved; nutritive value of the potato pulp is comprehensively improved; the potato pulp fermented feed has economic and environmental benefits.

Description

technical field [0001] The invention relates to the technical field of animal feed produced from plant materials. Background technique [0002] my country is the largest potato growing country in the world. In my country, in addition to direct consumption, potatoes are mainly used to produce starch. Every ton of potato starch produced will produce about 7000kg of fresh residue. The water content of fresh potato residue is as high as 90%. Dry matter contains a small amount of protein and a large amount of available components such as starch, cellulose, and pectin. If not utilized, it will not only cause waste of resources, but also cause pollution to the environment. If it is dried and used directly as animal feed, the cost is high and the protein content is low, the crude fiber content is high, and the palatability is poor. Therefore, the development of safe, efficient and effective potato residue value-added technology to improve its nutritional value and safety has both e...

In my country, in addition to direct consumption, potatoes are mainly used to produce starch. Every ton of potato starch produced will produce about 7000kg of fresh residue. The water content of fresh potato residue is as high as 90%. Dry matter also contains a small amount of protein and a large amount of available components such as starch, cellulose, and pectin. If not utilized, it will not only cause waste of resources, but also cause pollution to the environment.

If it is dried and used directly as animal feed, the cost is high and the protein content is low, the crude fiber content is high, and the palatability is poor.
